Hello all! I recently bought a 77 280z. Previous owner was doing a restoration to it.Interior is great, no cracks in dash or console, all panels in good shape too. Just needs carpet and new seats. Body is straight, just a few rust spots to contend with. Motor was replaced with one rebuilt with 10K on it. It started fine, idled a bit rough, when I give it throtle, the response is very slow and it will make a pop sound from the front. The rpm gauge slowly goes to about 2 thousand and then stays, doesn't move with engine rpm. Tried to drive it and it bogged and died. Won't start now. Has new battery. I'm an idiot about fuel injection, have no idea where to start with this. Here's a pic of the car.

first step get a fuel pressure gauge, hook it up after the fuel filter, then post findings.

Well, it started up the next morning again, but not going to try to drive yet. A more thorough look at things found some oddities.

1. distributors plug wires had #5 and 6 wrong.

2. dizzy was turned all the way to the right

3. put timing light on the no.1 and couldn't locate timing mark with the light. I looked at the pulley, and the only mark is one that was put there by PO? No groove or notch etc. on pulley to confirm with.

4. when I start the car, it pings from the motor, assuming it is a timing issue and best not to run it in this manner, I've parked it and am unsure of the best order of what to do to trouble shoot this.
